Dan Carpenter adba19f31c efi: Fix error handling in add_sysfs_runtime_map_entry() 
commit d67e199611 upstream.

I spotted two (difficult to hit) bugs while reviewing this.

1)  There is a double free bug because we unregister "map_kset" in
    add_sysfs_runtime_map_entry() and also efi_runtime_map_init().
2)  If we fail to allocate "entry" then we should return
    ERR_PTR(-ENOMEM) instead of NULL.
